Like all 205s, they're really rubbery (my grandfather had three of the bloody things). The cabrio never cocked it's back leg like the GTI, because the body flexed so much and my ex wife described being driven in one as "a bit like being a biscuit tin"

I wouldn't let her go.
Yes, I completely get that we should "keep calm and carry on", but this is all about risk and minimising it.
I spend half my life taking people out doing high risk outdoor activities. I am constantly assessing the situation the whole time I have a group out and I will regularly make the call that something we were planning to do is too high risk. If it was just me, I would do it, but when I'm assessing the risk to other people, I'll decide the risk is too high.
Right now, and for the next couple of weeks, especially around the election, London is too high risk to visit.
Alarmist or not, this is about your child.

Chrome OS has AV built in to it. That said, Windows has Windows Defender built in to it and there are dozens of AV providers out there! Never used a Chromebook, so can't say, although I use Google apps like Docs and Sheets - fine for fairly basic stuff and Sheets is great for web-based shared spreadsheets, but the functions are very limited compared to Excel. That said, IIRC, you just needed a straightforward laptop and the Chromebook seems ideal - and at £250 it's an absolute bargain!

They're all a bunch of useless twunts. May has been very cunning (like a fox she'd happily have ripped to pieces by dogs) in calling an election with no lead time. No opportunity for a Macron-like party to be founded and beat the sh*t out of the useless tories, labour and lib-dems.
